Hear is fantasy piece by the highly successful artist Kekai Kotaki. Firstly you will see that the figure in the image is bang on with the rule of thirds. The entire length of his body lies on the left hand guide line to this rule.
I also noticed The lighter distanced landscape follows the "L" rule around the top right hand corner, drawing more focus on the figure. I could say that it follows the vertical line in the cross rule, as there seems to be a definite change in colour intensity and light from left to right.
